PHONOGRAPH.

To all whom it may concern.'

Be it known that I, IVALTER H. MILLER,

a citizen of the United States, and a resident of Orange, count-y of Essex, and State ofv New Jersey, have invented' a certain new and useful Im 'urovement in Phonographs, of which the following is a description.

My invention relates to phonographs, and

articularly to phonograph horns and means or supporting the same.

In my application Serial No. 430,250, tiled May 1, 1908, I disclose a structure in which the horn is provided with a straight section arranged parallel to the path of the traveling carriage of the phonograph asthe latter traverses the record in reproducingr the saine. A tapered tube member connected to thc reproducer neck is arranged, in the above described application, to slide back and 'forth in the fixed tube above referred to with the movement. of the traveling carriage.l whereby bending and twisting stresses upon the telcscoping parts are avoided.

This application is an improvement on the above construction,'which consists chieliy in the provision of a. member slidably engaged within thc rigid tube member, and fitting snuglytherein, in whichinember t-he end of the tube section, which is attached to the reproducer neck, has a universal joint. By this means an improved jointV is provided between theyitelescoping parts whereby loss of air is prevented, while at the same time, the advantages accruing from the elimination of stresses are. retained.

In order that the inventio1-` may be fully understood. reference is hereby made to "the accompanying drawings, which forma part of this specification, whereinv Figure 1 represents my improved horn and connections applied to a phonograph, which latter is shown in dotted lines. and Fig. 2 is a detail sectional View ot the bearing member in the rigid tube enlarged to show the method of connect-ing together the parts of the saine.

In the drawings, the numeral 1. indicates the phonograph to which my improvement is applied. I have found it. convenient. to connect my rigid tube, which is arranged parallel to 'the path traversed by the phonograph reproducer to the phonograph by means of a4 bracket secured to the rear of the phonograph and extending upwardly undA Specification of Letters Patent. Application ined January "1s, 1909.

stant-ially on the central longitudinal line of the instrument and at the end thereof opposite the end gate or the end of the phonograph mandrel upon which the record` is inserted. The bell-shaped mouth piece of the horn is connected to the upper face of the bracket and is preferably so .mounted that it may be made to rotate in a horizontal plane as is common.

The bracket above described is represented by the reference numeral 2. The rigid tube, which is parallel to the path of' the reproducer is indicated by the numeral 3,and t-he bell shaped portion of the horn, which is connected to the' upper side of the bracket as above described, is represented by the refereri numeral 4. It is to be understood that whl el prefer to provide the common su}.iporting means for the mouth piece 4 and the rigid tube 3 in the neighborhood of one end of the instrument and ata short distance thereabove, this device may be supported from the phonograph cabinet by any convenient form of support as well as that which I have describedand shown. The

,member for connecting the neck of the reproducer 5 to the cylindrical tube 3 is designated by the reference numeral 6. This hollow member is preferably tapering in form and its smaller end is preferably removably connected to the reproducer neck 5 by means of the elbow 7. An outwardly projecting bead 8 is preferably formed upon the member 6. and serves to determine the position of the elbow thereon. The larger end of the member 6- is flared outwardly as indicated atff) into a partial spherical shape. This fits snugly within the shoe or sliding member l0 which slidingly engages within the rigid tube 3. a ball and socket or universal joint being thereby provided betWeent-he member 0 and the shoe 10, allowing the easy removal of the elbow 7 from the reproducer neck 5.

In the construction indicated. the shoe 10 is formed of two members 11 and 12 in order that the same may be easily fitted to the spherical end 9 of the tube 6, although any other convenient method of forming this joint may be used. Asndicated, the members 11 and 12 maybe placed on the outsideof the spherical end 9 of the tube 6 and may conveniently be secured' togethery as by screw thread en agement of a i'ange on.

the sections 11 an 12, as indicated'at 13 'in Fig. 2. The end 9 of the tube 6 with the Ashoe 10 carried thereby may then be inserted within the end of'the rigid tube 3 in which it is then adapted to slide in the course of the forward and backward travel.

engage the feed nut from the screw and is' pushed back to its original position.

It will. be noted that with the device shown, ahorn of any convenient size may be used, since, when the horn is turned so as 'graph cabinet serves as a supporting piece. for the horn, rendering it practically impos to be directed endwise of the phonograph, as shown, vthe entire length of the phonosible to overturn the cabinet by the use of a horn of' any reasonable size. The horn, however, may be turned in any desired direction as is evident.

Having now described my invention,what I claim and desire to secure by Letters Patent of the United States is as follows:

` 1. In a phonograph, the combination with a horn section and means for supporting the same, of a movable reproducer, and telescoping connectionsbetween the horn Section :ind the reproducer, comprisinga .tube fixed with its longitudinal `,airis parallelto the path traversed by the reproducer inits movement, anannular shoe slidably mounted in said tube, and `a hollow ,tapermgmem- -ber Pivotally connected with said shoe andl communicatm with the reproducer, substantially as ascribed.

2. In a phonograph, the combination with a horn section and means for supportingthe same, of a movable reproducerj and telescoping connections between the horn section and the reproducer, comprising a tube fixed-with its .longitudinal axisl aralllel to the path traversed by the repro ucer in its movement, a shoeJ slidably mounted in said tube,and a tube communicating with the reproducerand having a ball and socketconnection with -said shoe, substantially as described.

3. In a phonograph, the combination with a horn section and means for supporting the same, ofa movable reproducer, and telescoping connections between the horn sec- `tion and the reproducer, comprising a tube fixed with its longitudinal axis parallel to the path traversed by. thereproducer in its movement, annular members slidably mount-v ed in said tube, and a tube communicating with the reproducer and having an enlarged rounded end embraced by said annular members to constitute a ball and socket joint,

substantially as described. v

4. In a phonograph, the combination with `a horn section and'means for supporting the same, of a movable reproducer, and telescoping connections between the horn section and the reproducer, comprising a fixed tube, a member slidably mounted in said tube, and a tube communicating with the reproducer and having a ball and socket connection with said member, substantially as described.

This specification signed and witnessed this 16 day of January 1909.
